What is the role of water in compaction?

· What is the role of water in compaction?

Moisture content plays very important role in densification of soil.

When the moisture content is low, the material is stiff and difficult to compress and the dry soil density is low , when the moisture content is increased, soil particles are lubricated and the soil becomes soft, plastic and easier to compaction. Thus, the dry soil density increased and reaches a maximum.

Write the names of different types of flow

Write the names of different types of flow and explain them. The fluid flow is classified as:- 1. Steady and unsteady flow 2. Uniform and non-uniform flow 3. Laminar and turbulent flow 4. Compressible and incompressible flow 5. Rotational and irrotational flow 6. One,two and three dimensional flow (1). Steady flow:- Study flow is defined as flow types in which fluid characteristics like velocity, pressure, density, etc. at a point do not change over time. Unsteady flow:- Unsteady flow is the type of flow in which the speed, pressure or density at a point changes over time. (2). Uniform flow:- Uniform flow is defined as the type of flow in which the velocity does not change in space at any point. ...
